    I quickly tried your changes.
    Some notes
    (1)  When listing the yarn-session.sh cli options, I could not see the newly added argument
    ```
    ./bin/yarn-session.sh 
    2016-06-10 09:28:37,186 ERROR org.apache.flink.yarn.cli.FlinkYarnSessionCli                 - Missing required argument n
    Usage:
       Required
         -n,--container <arg>   Number of YARN container to allocate (=Number of Task Managers)
       Optional
         -D <arg>                        Dynamic properties
         -d,--detached                   Start detached
         -jm,--jobManagerMemory <arg>    Memory for JobManager Container [in MB]
         -nm,--name <arg>                Set a custom name for the application on YARN
         -q,--query                      Display available YARN resources (memory, cores)
         -qu,--queue <arg>               Specify YARN queue.
         -s,--slots <arg>                Number of slots per TaskManager
         -st,--streaming                 Start Flink in streaming mode
         -tm,--taskManagerMemory <arg>   Memory per TaskManager Container [in MB]
    Error while starting the YARN Client. Please check log output!
    ```
    
    (2) Starting a YARN session works. Also, connecting with a second YARN session works. However, if I'm stopping the session from the second session client, the first one does not notice this.
    It would be good if all connected clients receive the messages, instead of the last one connected.
